The velocity is always _____ to the line of a circle. 

• outwards

• towards the center

• tangent

• faster

A particle is moving in a circular path of radius r.

The displacement after half a circle would be:

• Zero

• πr

• 2r

• 2πr

Centripetal force is...

• the inward force acting on a body moving at constant speed in a circle

• the outwards force acting on a body moving at constant speed in a circle

An object moves in a circular path at a constant speed.  Compare the direction of the object's velocity and acceleration vectors.    
Both vectors point in the same direction.  
The vectors point in opposite directions.  
The vectors are perpendicular.  
The question is meaningless, since the acceleration is zero

• Both vectors point in the same direction.

• The vectors point in opposite directions.

• The vectors are perpendicular.

• The question is meaningless, since the acceleration is zero
